VirtualBox and Intel Core 2 processors?

[Tomservo]

Using OpenSolaris 2008.05 RC2a (based on snv_86), I don't seem to be able to run any code that switches into protected mode. While it worked fine on my old Athlon X2 4200+, my new machine, which has a Core 2 Quad 9450, just aborts the VM.

What could be the problem?

Solaris runs in 64bit mode, I've enabled VT-x. I've tried running OpenSolaris, Ubuntu as well as Windows Server 2003 in a VM, all abort as soon they initialize the kernel, or in case of Windows, when the setup is done loading the system files and starts the kernel.

If I had to guess, VirtualBox isn't able to figure out the processor type and enable VT-x. Disabling it doesn't even result in a warning and it starts the VM nonetheless.
